Abstract: A rocker mill includes a rollstand (15) and a carriage (12) for supporting and repositioning a workpiece (14) extending through the rollstand. A first hollow-shafted electric motor (49) is mounted on the carriage and includes a first hollow open-ended (94) rotor and threaded nut through which the stationary feedscrew (32) passes. The threaded nut is connected to the first motor to be rotated thereby in order to move the carriage longitudinally toward the roll stand. A second hollow-shafted electric motor is mounted on the carriage and includes a second hollow open-ended rotor and a clamp through which the workpiece passes. The clamp (50) is actuated into clamping engagement with the workpiece for transmitting rotational and longitudinal movements thereto. Such mechanism for imparting rotary and longitudinal movements to the workpiece is of very low inertia and thus is able to reposition the workpiece with a high degree of precision.

Abstract: The invention proposes a quick action coupling consisting of two parts (A,B) of essentially symmetrical construction. Each part of the quick action coupling has an annular valve housing (2,18) in the interior of which is secured a cone guide (6,22) which guides a movable valve cone (11,27). An annular cup packing (13,29) of flexible material with embedded segments engages over sections of the valve housing. In the uncoupled condition, the valve cones press sealingly against the inner wall of an angled front face (2a,13a) of the valve housing and the cup packings engage over the valve cones. In the coupled condition, the valve cones and the front faces of the cup packings press against one another, fluid-carrying annular channels (31) thereby being formed between the valve housings and valve cones and between the cup packings and the valve cones. <IMAGE>

Abstract: A magneto-optical recording device has a flying head (11) that floats over a magneto-optical disk according to the rotation of the magneto-optical disk. The flying head includes a head slider. A solid lubricant (13) is applied to the bottom surface of the head slider facing the magneto-optical disk. Since the solid lubricant makes the flying head contact with the magneto-optical disk smoothly, the scratching and wear of the magneto-optical disk and the flying head decrease. Therefore, the reliability and the durability of the magneto-optical recording device can improve. Physical protrusions and recessions or holes containing fluorocarbon oil therein may be formed instead of the solid lubricant. In this case, the contact area between the flying head and the magneto-optical disk is also smaller than the case where physical protrusions and recessions are not formed. In addition, with a configuration such that thin-film layers made of a fluorocarbon resin having an excellent lubricity are formed on both sides of the bottom surface of the head slider, since the magneto-optical disk comes into contact with the head smoothly, the reliability and the durability of the magneto-optical recording device can improve.

Abstract: A data processing system maintains logs for system and media recovery. The logs contain state identifiers each uniquely identifying the state of a corresponding section of a storage medium, such as a disk. The state identifiers are assigned after changes have been made such that they can be determined from the information in the logs. One implementation involves assigning state identifiers in a known sequence, such as in a monotonically increasing sequence of integers beginning with zero.

Abstract: The present invention provides a vacuum gauge having two integrated circuits connected in a half bridge circuit to register subatmospheric gas pressure from a change in thermal gas conductivity. One of the integrated circuits serves to generate an electrical current proportional to the ambient temperature and a function of its power output conducted by the gas. The other of the integrated circuits acts as a reference to generate an electrical current proportional to ambient temperature. The half bridge circuit acts to subtract the currents so that subatmospheric pressure can be read on an ammeter as a function of gas thermal conductivity.
